Demographic and clinical profile of patients suffering prolonged severe hypoxia in COVID-19.

Background: Coronavirus disease 2019 (COVID-19) may result in rapid onset of hypoxemic respiratory failure. This study aimed to characterize the factors and outcomes associated with prolonged hypoxia in patients with COVID-19. Prolonged severe hypoxia (PSH) was defined as hypoxia requiring ≥6 L/min of oxygen by nasal cannula or equivalent for more than 10 days.

Invasive hemodynamic parameters in patients with hepatorenal syndrome.

Background: Hepatorenal syndrome (HRS), a form of kidney dysfunction frequent in cirrhotic patients, is characterized by low filling pressures and impaired kidney perfusion due to peripheral vasodilation and reduced effective circulatory volume. Cardiorenal syndrome (CRS), driven by renal venous hypertension and elevated filling pressures, is a separate cause of kidney dysfunction in cirrhotic patients. The two entities, however, have similar clinical phenotypes.

Comparison of Patient Clinical characteristics and Outcomes Between Different COVID-19 Peak Periods: A Single Center Retrospective Propensity Matched Analysis.

Introduction While Coronavirus disease 2019 (COVID-19) specific treatments have been instituted, overall mortality rates among hospitalized patients remain significant. Our study aimed to evaluate patient clinical characteristics and outcomes comparing the different COVID-19 infection peak periods. Methods This is a retrospective study of all adult patients hospitalized with a confirmed diagnosis of COVID-19 between March 1 to April 24, 2020 and November 1 to December 31, 2020, which corresponded to the first and second waves of COVID-19 infection in our institution, respectively.
